气调保鲜袋和乙烯脱除剂对冰温贮藏桃品质的影响

在冰温贮藏的基础上,研究气调保鲜袋及乙烯添加剂在冰温贮藏条件下对桃果实品质的影响。实验结果表明,冰温条件下采用气调保鲜袋可降低桃的腐烂指数,增加VC和可滴定酸的含量。添加乙烯脱除剂可推迟桃果实的后熟衰败,减少桃果实在贮藏期内的腐烂,但是它抑制了总糖的合成和胞壁物质的降解,使果实口感变淡,果实在后期不能正常软化。

Effect of modified atmosphere bag and ethylene desorption agent on quality in peach during hyo-on storage

The experiments were conducted to investigate the effects of modified atmosphere bag and ethylene desorption agent on peach during hyo-on storage.The results indicated that modified atmosphere bag lowered decay index,increased VC and titratable acid.Adding ethylene desorption agent could delay after-ripening and decline of peach,reduce decay during storage.But it suppressed the synthesis of total sugar and the material’s degradation of cell wall,the fruit tasted became weak,fruit in the later could not normal softening.
